sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.
Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.
In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported. In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.

- Fix a couple of LORs and panics;
- Temporarily remove the code that tries to cleanup sockets that stuck
on accepting queues (both complete and incomplete). I'm taking an ostrich
approach here until I find a better way to deal with sockets that were
disconnected before accepting (i.e. while socket was on complete or
incomplete accept queue).
soreceive(), and sopoll(), which are wrappers for pru_sosend,
pru_soreceive, and pru_sopoll, and are now used univerally by socket
consumers rather than either directly invoking the old so*() functions
or directly invoking the protocol switch method (about an even split
prior to this commit).
This completes an architectural change that was begun in 1996 to permit
protocols to provide substitute implementations, as now used by UDP.
Consumers now uniformly invoke sosend(), soreceive(), and sopoll() to
perform these operations on sockets -- in particular, distributed file
systems and socket system calls.

function, pru_close, to notify protocols that the file descriptor or
other consumer of a socket is closing the socket. pru_abort is now a
notification of close also, and no longer detaches. pru_detach is no
longer used to notify of close, and will be called during socket
tear-down by sofree() when all references to a socket evaporate after
an earlier call to abort or close the socket. This means detach is now
an unconditional teardown of a socket, whereas previously sockets could
persist after detach of the protocol retained a reference.
This faciliates sharing mutexes between layers of the network stack as
the mutex is required during the checking and removal of references at
the head of sofree(). With this change, pru_detach can now assume that
the mutex will no longer be required by the socket layer after
completion, whereas before this was not necessarily true.

use this ioctl to obtain the list of HCI nodes. User-space application
is expected to preallocate 'ng_btsocket_hci_raw_node_list_names' structure
and set limit in 'num_nodes' field. The 'nodes' field should be allocated
as well and it should have space for at least 'num_nodes' elements.
The SIOC_HCI_RAW_NODE_LIST_NAMES should be issued on bound raw HCI socket.
It does not really really matter what HCI name the socket is bound to, as
long as it is not empty.

rather than an error. Detaches do not "fail", they other occur or
the protocol flags SS_PROTOREF to take ownership of the socket.
soclose() no longer looks at so_pcb to see if it's NULL, relying
entirely on the protocol to decide whether it's time to free the
socket or not using SS_PROTOREF. so_pcb is now entirely owned and
managed by the protocol code. Likewise, no longer test so_pcb in
other socket functions, such as soreceive(), which have no business
digging into protocol internals.
Protocol detach routines no longer try to free the socket on detach,
this is performed in the socket code if the protocol permits it.
In rts_detach(), no longer test for rp != NULL in detach, and
likewise in other protocols that don't permit a NULL so_pcb, reduce
the incidence of testing for it during detach.

than an int, as an error here is not meaningful. Modify soabort() to
unconditionally free the socket on the return of pru_abort(), and
modify most protocols to no longer conditionally free the socket,
since the caller will do this.
This commit likely leaves parts of netinet and netinet6 in a situation
where they may panic or leak memory, as they have not are not fully
updated by this commit. This will be corrected shortly in followup
commits to these components.

following the protocol pru_listen() call to solisten_proto(), so
that it occurs under the socket lock acquisition that also sets
SO_ACCEPTCONN. This requires passing the new backlog parameter
to the protocol, which also allows the protocol to be aware of
changes in queue limit should it wish to do something about the
new queue limit. This continues a move towards the socket layer
acting as a library for the protocol.
Bump __FreeBSD_version due to a change in the in-kernel protocol
interface. This change has been tested with IPv4 and UNIX domain
sockets, but not other protocols.
panic. The panic happens when outgoing L2CAP connection descriptor is
deleted with the L2CAP command(s) pending in the queue. In this case when
the last L2CAP command is deleted (due to cleanup) and reference counter
for the L2CAP connection goes down to zero the auto disconnect timeout
is incorrectly set. pjd gets credit for tracking this down and committing
bandaid.

there are at least two versions of the adapter. Version 1 (product ID 0x2200)
of the adapter does not work with ng_ubt(4) and require special driver and
firmware. Version 2 (product ID 0x3800) seems to work just fine, except it
does not have bDeviceClass, bDeviceSubClass and bDeviceProtocol set to required
(by specification) values. This change forces ng_ubt(4) to attach to the
version 2 adapter.
